This may seem New-Age-y but the roots of these ideas are found in many traditional practices, like Ayurveda, where the underlying assumption is that all levels of our being reflect one another.
In this videoI talk with Stacy Vajta of Expanded Pathways and Elicia Woodford of Awakening360 about Candida, or Krumi, but every 'dis-ease' of mind needs to be healed by creating balance in the body and every dis-ease of the body is ultimately mirroring something going on in the subtle levels.

How do we work with this on a practical, at-home level? Notice how you feel when you eat, exercise, fall asleep. These emotional energetic states will determine how the food or experience you are taking in effects your body. If you eat that piece of cake with an attitude of reverence and calm appreciation it will have a very different effect on your body then if you eat it with a feeling of guilty shame or self loathing. Normal body processes are clearly impacted by our emotional states. This is why cultivating Sattwa, or calm alertness, is a life-long goal.

Towards this end we can:

Take foods and herbs that that calm the mind and avoid those that aggravate it.

Maintain regularity in our daily schedules. Both mind and body are soothed by knowing what comes next.

Have a regular meditation practice and cultivation of consciousness in everything we do and feel.
